Answer:
Hi. You have not informed the experiment that this question relates to, making it difficult to respond to your query. However, I looked up your query on the internet and found one similar to yours that included an experiment that measured the volume of balloons inflated by people's breath.
The volume of the balloons remains constant throughout the number of tests, according to the results of the experiment. This is due to the fact that when we blow, our lungs prefer to express the same amount of air as when we breathe in regular settings. This is most likely due to the fact that all of the balloons were filled with air when the participants were in the same physical and mental condition, i.e., calm and still, causing the volume of air they breathed and emitted to remain constant. If the individuals in the experiment were exerting some physical effort or were stressed and concerned, the amount of air would be different.

Some organisms have genes that improve their ability to survive
Some organisms have genes that improve their ability to survive and reproduce. If the gene also help their offspring survive and reproduce, then frequency in gene in population get increase.
What is gene?A gene is the basic physical and functional unit of heredity. Genes are made up of DNA and each chromosome contains many genes.
Throughout the individual lives, their genomes interact with their environments to cause variations in traits which help an organism to adapt better to the environment. These changes which help the organism's survival are selected and passed on to next generation. The genes help in increasing the fitness of the organism and thus the gene frequency changes. . The frequency of these gene increases as they are selected favourably.

Use the mitosis and meiosis interactive to help you identify the images as a cell in metaphase of mitosis, meiosis I, or meiosis II. All cells come from an organism that has a diploid (2n) chromosome number of eight.
In this case, the images are not found here but a cell in meiosis has undergone a reduction in the genetic material.
What is meiosis?Meiosis is a reductional type of cell division where chromosome number is reduced to half (haploid number n: 4).
In this case, meiosis will produce four cells having 4 chromosomes each (2n: 8 chromosomes in mitosis).
In conclusion, the images are not found here but a cell in meiosis has undergone a reduction in the genetic material.

Describe what happens when blood glucose levels are not kept stable.
Blood glucose levels should be kept stable in the body because :-
A rise in glucose level can cause diabetes mellitus or simply diabetes due to too much glucose in the blood stream.In this patients pass urine too much loaded with sugar. Also he feels thirsty due to too much loss of water and becomes weaker and weaker.A fall in glucose level can cause hypoglycemia.
Even a little fall of glucose level in the bloodstream can bring a patient in a state of coma. The person gets frequent headaches, vomiting, dizziness, etc.The regualtion of glucose in the body is done by two main hormones secreted by an endocrine gland called pancreas.
These two hormones are - Insulin and Glucagon.Insulin lowers the glucose level in the body whereas, Glucagon helps in increasing it.Therefore, the glucose level should be always kept stable in the body.

From the illustration, it can be said that the age of the rock layer is the same in the four locations of index fossil 1.
Age of fossilIt is a measure of how long a material has been fossilized.
Thus, if a rock layer contains a fossil and another similar rock layer does not have the fossil, one can conclude that the ages of the rock layers are different.
Only index fossil 1 is found in all the four locations as shown in the image. Hence, one can as well infer that the rock layers in all these four locations are of the same age.

Jayden is researching the Earth's
plates. How would he describe the
relationship between the Earth's plates
and soil and rocks?
Answer:
Geologists have hypothesized that the movement of tectonic plates is related to convection currents in the earth's mantle. Convection currents describe the rising, spread, and sinking of gas, liquid, or molten material caused by the application of heat.
The Earth's plates have a crucial relationship with soil and rocks. This connection is characterized by the plates' movement influencing the formation, distribution, and composition of soil and rocks across the planet.
The asthenosphere, which is semi-fluid beneath them, is separated into many tectonic plates that make up the Earth's lithosphere. Convective currents in the mantle cause these plates to move constantly. Processes like subduction, in which one plate falls beneath another, and rifting, in which plates move apart, are fueled by this movement. Mountains, valleys, and oceanic basins are all the result of these dynamic processes, which have a significant impact on the surface of the Earth.
Through volcanic activity and metamorphism, interactions between the plates also aid in the production of different types of rocks. Therefore, the distribution and makeup of soils and rocks on our globe are significantly shaped by plate movement, which also has an impact on landscapes, ecosystems, and geological characteristics.
